tax in different countries

Tax numbers specific per country.


Using tax identification numbers, several nations’ tax authorities are able to trace and monitor individual tax accounts. Although the UK does not have a tax ID number, it does utilise two numbers that are assigned to members of the public and have a similar duty to that of a tax ID number in the United Kingdom.

UK alternatives to a tax identification number 

There are two TIN-like numbers in the United Kingdom, however, they don’t appear on any official identifying documents and are included in a wide range of government correspondence.


Individuals and businesses that are required to file and submit a tax return are given a unique taxpayer reference (UTR) — a 10-digit collection of digits. In spite of the fact that the UTR is prominently shown on a tax return and other HMRC communication, the UTR is not printed or furnished in its own right.


NINO stands for “National Insurance Number,” and each person who has it has it just once. It consists of two letters followed by six digits and one of the letters A, B, C, or D. People who live in the UK on a regular basis are automatically assigned a NINO or can request one. A NINO, which will be used on a variety of official papers for the remainder of a person’s life, will be automatically provided to a young adult turning 16 years old.


An official letter from the Department for Work and Pensions or HMRC will tell an individual that they have been assigned a NINO. A NINO is “not proof of identification” in any situation, and hence it cannot be used to authenticate the identity of any individual, according to the letter sent to the receiver. On some official papers addressed to HMRC, it can, nevertheless, be cited as a tax identification number. One thing to keep in mind about the UTR and the NINO is that once they are assigned, they remain assigned indefinitely. This is a one-of-a-kind number that will never change in either format or detail.

Do all UK residents get a UTR or NINO?

All inhabitants of the United Kingdom, as well as British nationals, are assigned a unique identifier (UTR or NINO). A PAYE temporary reference number may be granted to an individual if a NINO has been lost or cannot be found. HMRC will generate this reference number for the individual. For example, 11M11111 would consist of two digits, a letter, and five numerals.

Under which circumstances may a tax identification number not be issued?

Some citizens and nationals of the United Kingdom are not automatically given Taxpayer Identification Numbers (TINs). Certain UK residents, including those under the age of 16 and those who aren’t allowed to work in the country, will not be granted a Taxpayer Identification Number (TIN).



Citizens, lawful permanent residents, and foreign nationals who enter the country under a visa category that allows them to work in the United States are all issued Social Security numbers by the Social Security Administration (SSA) (e.g., students on J-1 and F-1 visas are authorised to work in the U.S. and are eligible for SSNs). There are specific rules for employees and fellows regarding tax identification numbers.

TIN Description

The Social Security Number (SSN) and the Employer Identity Number (EIN) are the two types of U.S. taxpayer identification numbers that are granted to individuals and businesses. Those who are obliged to have a U.S. taxpayer identification number but do not have or are not eligible to receive an SSN are granted an Individual Taxpayer Identification Number (ITIN). All tax returns and other papers received to the IRS must include a taxpayer identification number (SSN, EIN, or ITIN). In addition, a taxpayer’s taxpayer identity number must be provided to anybody else who uses the taxpayer identification number on any IRS-received returns or documents.

It doesn’t matter if you’re a US citizen or a non-citizen if you have a US filing or reporting obligation under the Code. In order to get an ITIN, individuals must complete a filing requirement and submit a legitimate federal income tax return.

The format of an SSN is as follows: xxx-xx-xxxx. In the first three numbers, there is a geographic relevance, the following two digits have no meaning and are issued consecutively, and the remaining four digits are completely unrelated. xx-xxxxxxx is the format for an EIN.


The nine-digit ITIN number has the following format: 9xx-xx-xxxx and always begins with the number 9.

Where to find TINs? 

As with an SSN, the Taxpayer Identification Number (TIN) may be found on a variety of government-issued papers, including tax returns and other forms submitted to the Internal Revenue Service (IRS). Taxpayer Identification Numbers (TINs) are regarded as private and confidential in the United States. According to section 6103 of the Code and, in some cases, the confidentiality provisions of the relevant tax treaty or other bilateral agreement for information exchange, TINs are protected from disclosure when they are provided to the IRS by a foreign government under such treaty or agreement when the information is provided to the IRS under such treaty or agreement.
